Troubleshooting 

This LCD Monitor has pre-adjusted using factory to standard VGA timings. Due to the 
output timing differences among various VGA cards in the market, users may initially 
experience an unstable or unclear display whenever a new display mode or new VGA 
card is selected. 

ATTENTION 

This LCD Monitor Supports Multiple VGA Modes.   
Refer to the Standard Timing Table for a listing of modes supported by this LCD Monitor. 

PROBLEM       

Picture is unclear and unstable or new colorized

 

The picture is unclear and unstable, please perform the following steps: 

1.  Enter PC to “Shut Down Windows” status while you’re in a MS-Windows 

environment. 

2.  Check the screen to see if any black vertical stripes appear. If there are, use the 

“Clock” function in OSD menu and adjust (by increment or decrement numbers) until 
those bars disappear. 

3.  Move to ”phase” function in OSD menu again and adjust the monitor screen to its 

clearest display. 

4.  Click “No” on ”Shut Down Windows” and return to the normal PC operating 

environment. 

PROBLEM      There is no picture on LCD Monitor

 

If there’s no picture on the LCD Monitor, please perform the following steps: 

1.  Make sure the power indicator on the LCD Monitor is ON, all connections are 

secured, and the system is running on the correct timing.    Refer to Chapter 3 for 
information on timing. 

2. 

Turn off the LCD Monitor and then turn it back on again.    Press the right Function 
Select Control button once and then press either the left or right Adjustment Control 
button several times. If there is still no picture, press the other Adjustment Control 
button several times.     

3. 

If step 2 doesn’t work, connect your PC system to another external CRT.    If your 
PC system Functions properly with a CRT Monitor but it does not function with the 
LCD Monitor, the output timing of the VGA card may be out of the LCD’s 
synchronous range.    Please change to an alternative mode listed in the Standard 
Timing Table or replace the VGA card, and then repeat steps 1 and 2.     

PROBLEM   

There is no picture on LCD Monitor

   

If you have chosen an output timing that is outside of the LCD Monitor’s synchronous 
range (Horizontal: 24 ~ 80 KHz and Vertical: 56 ~ 75 Hz), the OSD will display an “Input 
Signal Out of Range” message.    Choose a mode that is supported by the LCD Monitor. 
If there is no signal input or you get a DPMS power saving signal from the PC, the 
monitor will display the message “No Input Signal”, and then go into the POWER OFF 
mode. 
If the signal cable is not connected to the monitor, the monitor will display the message 
“Check Video Cable”, and then go into POWER OFF mode.
